<P>PROBLEM TO BE SOLVED: To previously obtain a dilution ratio of a dilution internal standard liquid by referring to a value each time, to determine whether a variation is within a normal range, and to determine whether the variation is abnormal. <P>SOLUTION: An electrolyte analyzer 400 comprises: a dilution vessel 131 for mixing a sample and a dilution liquid, and generating a dilution sample solution; a sample supplying means for supplying the sample to the dilution vessel 131; a dilution liquid supplying means for supplying the dilution liquid to the dilution vessel 131; a measurement means for extracting the dilution sample solution from the dilution vessel 131, and measuring a concentration of an electrolyte as a to-be-measured component contained in the dilution sample solution; a calculation means for calculating the dilution ratio of the dilution internal standard liquid; an internal standard liquid supplying means for supplying the internal standard liquid to the dilution vessel 131; and a drive plate 171 for coupling a dilution liquid supplying pump 122, an internal standard liquid supplying pump 162 and a waste liquid pump 153. A salt containing the same ion as the fixed quantity of the to-be-measured component is added to the dilution liquid. <P>COPYRIGHT: (C)2010,JPO&INPIT |
